Fix PSTN_CALLER extraction — CHANNEL(peername) isn't valid on this Asterisk build

Browse Source 
Confirmed live: "Unknown or unavailable item requested: 'peername'" left
PSTN_CALLER empty, which made AST_CONFIG() error ("requires a category")
and PSTN_TIER come back empty too — every call fell through to "no PSTN
permission" and got busy-signaled regardless of the extension's actual
tier. Replaced with CUT(CHANNEL,/,2) then CUT(...,-,1), extracting the
endpoint name from the channel name itself (e.g. "PJSIP/201-00000006" ->
"201") — a plain string operation with no dependency on which channel
function items this particular Asterisk build supports.
